gcc4 build fix.

* offsetof is not allowed on non-POD types so we need to use
offset_of_member (gcc2 accepts offsetof, and C++11 relaxed the
constraints on where it is allowed so it should work there too)
* we have offset_of_member as a workaround until we switch to C++11,
move it from khash (which is soon to be removed) to list.h which is the
other place where it is used (for this one single call in our whole
codebase)

Also fix a typo in vfs.cpp.

* The C "struct list" and the C++ DoublyLinkedList implementations had mixed
next/prev link order - that messed up the DoublyLinkedListCLink adapter.
* Since it's more likely that someone messes with the C version, the C++ version
now uses the same order than that one.
* This fixes a bug when TCP's BufferQueue tried to iterate over a list, messing
up its integrity.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22676 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added a list_get_last_item() call - one day we should make most of them inline.
Or use the C++ list implementation where possible.

* Added a new list_insert_item_before() function that inserts a new item
before another one in the list.
* The video modes in the boot loader are now sorted (by resolution, larger
resolution comes first). Doubled entries are automatically removed; this
fixes bug #192.

Fixed a typo, thanks to Jack Burton for pointing this out.

Added a call to move the contents of one list to another.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6957 a95241bf-73f2-0310-859d-f6bbb57e9c96

Moved list.h to the util/ subfolder. (It currently still is in the kernel
private headers directory to not break the build.)
